Analysis of the role of the late‐flowering locus, GI, in the flowering of Arabidopsis thaliana Article in The Plant Journal 3(2) - September with 51 Reads How we measure 'reads'. To ascertain whether intraspecific variability might be a source of information as regards the genetic controls underlying plant leaf morphogenesis, we analyzed variations in the architecture of vegetative leaves in a large sample of Arabidopsis thaliana natural races. A total of accessions from the Arabidopsis Information Service collection were grown and qualitatively classified into
Introduction. Arabidopsis thaliana, a facultative long-day plant, occurs throughout the northern hemisphere, and wild accessions show extensive variation in several traits including flowering time .The major environmental factors that control flowering time are light quantity (day length) and quality, ambient growth temperature, and vernalization. Furthermore, genetic analysis has been very successful in elucidating salt stress responses in the budding yeast (Saccharomyces cerevisiae; for review, see Zhu et al., ). The application of Arabidopsis genetics on plant salt tolerance studies is beginning to shed light on novel tolerance mechanisms operating in plants.
Two loci FRI (FRIGIDA) and KRY (KRYOPHILA) have previously been identified as having major influences on the flowering time of the late-flowering, vernalization-responsive Arabidopsis ecotype, Stockholm. We report here on the mapping and subsequent analysis of these two loci. FRI was mapped to the top of chromosome 4 between markers w and m, using restriction fragment length .

The small ephemeral species Arabidopsis thaliana grows under a wide range of temperature and day-length conditions across much of the Northern hemisphere, and a number of flowering-time loci that vary between different accessions have been identified before.

are two ways to approach the genetic system of flowering time: 1. analysis of natural variation, and 2. analysis of artificial, that is mutagen-induced variation.
When crossing natural varieties of Arabidopsis, one generally finds in segre gating generations typical quantitative variation (continuous variation) for flowering time and leaf.
Also, genetic analysis of Arabidopsis varieties showing natural variation in flowering time has demonstrated how the activity of these pathways can be altered in nature and how balancing the effects of different environmental stimuli on flowering time is important in plants adapting to growth in different geographical locations.

This is illustrated by reviewing current research in two different biological fields: flowering time and plant growth. The analysis of Arabidopsis natural variation for flowering time revealed the. Flowering time variation measured at 10 and 16°C in the 1,genomes Arabidopsis thaliana collection of natural accessions were used as a model.
The polygenic architecture of flowering time was defined as the 48 loci that were significantly associated with flowering time—at 10 and/or 16°C and/or their difference—in this population. H.A.S.

(Wageningen), (), pp. Systematic genetic and genomic analysis revealed extensive allelic variation in FRI/FLC that was proposed to explain a large fraction of the phenotypic variation in flowering time among Arabidopsis accessions (Weigel, ).
WHAT WAS SHOWN. The summer annual habit of Arabidopsis can arise from the loss of FRI function, resulting in FLC alleles that are no longer up-regulated by FRI or a weak FLC allele. In this work by Gazzani et al. (), rapid-cycling accessions of Arabidopsis were analyzed to determine the cause of the early lly, the study focused on FRI variation among five accessions.
We have examined the late-flowering behavior of two ecotypes of Arabidopsis thaliana, Sf-2 and Le The late-flowering trait segregates as a single dominant gene in crosses with the early-flowering Columbia ecotype.
This gene, which we refer to as FLA, is located at one end of chromosome 4 between RFLP markers and and is thus distinct from previously mapped genes that affect. Arabidopsis thaliana is a first class model organism and the single most important species for fundamental research in plant molecular genetics.

It is a small plant that has a short generation time (∼6 weeks), and grows well under laboratory conditions, on shelves at room temperature, with limited amounts of light.Flowering Time Analysis.
For the flowering time analysis, 72 accessions of Arabidopsis (Arabidopsis thaliana) from the Altmann and the Nordborg collection and 31 mutants and transgenic lines were selected (Supplemental Tables S1 and S2).
The accessions were taken through one generation of single seed selection to further reduce variation. Genetic analysis in haploids provides unconventional yet powerful advantages not available in diploid organisms.
In Arabidopsis thaliana, haploids can be generated through seeds by crossing a wild.
